As emperor, Alexander's peace time reign was prosperous. However, Rome was militarily confronted with the rising Sassanid Empire and growing incursions from the tribes of Germania.
He succeeded his cousin Elagabalus in 222, and was ultimately assassinated himself, marking the epoch event for the Crisis of the Third Century — nearly 50 years of civil wars, foreign invasion, and collapse of the monetary economy, though this last part is now disputed.
